Explanation:

 Sree Narayana Guru was born in an Ezhava Family in A.D.1856 in the then Indian Native state of Travancore.

He was born into a Ezhava family in an era when people from such communities, which were regarded as Avarna, faced much social injustice in the caste-ridden of Kerala. He led a reform movement in Kerala, rejected casteism, and promoted new values of spiritual freedom and social equality.
